Maintenance (Mower)
Cleaning of Mower Unit
Important
While cleaning, do not allow water on the
sealed parts of the reel shaft. (Avoid high-
pressure water cleaning.)
Otherwise, it may cause damage to the
machine.
Be sure to clean the mower unit after use.
Stop the engine, and then remove the key.
Carefully clean the front and back of the
mower unit with water or compressed air.
Remove any grass wrapped around the reel
cutter (cutting cylinder).
Adjusting CAM
Turn the cam bush on both sides of the bottom
blade, and the blade can be raised and
lowered respectively by maximum 0.3 mm
(0.012 in).
The above method is used when the edges of
the reel cutter (cutting cylinder) and the bed
knife (bottom blade) are not in parallel.
Check for the gap between the reel cutter
(cutting cylinder) and the bed knife (bottom
blade)
When the gap appears on the left side.
Loosen the locknut and turn the left cam
bush clockwise to eliminate only the gap
distance.
When you raise the bed knife (bottom
blade) by 0.1 mm (0.004 in), turn the left
cam bush clockwise 30 degrees.
Once the adjustment completed, tighten
the locknut securely.
When the gap appears on the right side.
Loosen the locknut and turn the right cam
bush anticlockwise to eliminate only the
gap distance.
Once the adjustment completed, tighten
the locknut securely.
Note:
The figure below shows the situation when you
see from the left side.
The right side is mirror reversed.
